Abstract

A longitudinally adjustable vehicle seat (1) includes a lower rail (5) and a longitudinally displaceably guided upper rail. A lower rail mounted end stop (40, 40b) delimits a comfort adjustment region interacting with an upper rail mounted stop element (36). The upper stop element (36) can be displaced beyond the comfort adjustment region into an easy entry region and is part of a stop module (30) that is pivotable about a pivot axis (S). The stop module (30) includes a deflector element (34) that moves upwards, when the stop element (36) has not been shifted away, in the vertical direction upon contact with a screw head (22) that is located in the cavity between the upper rail (3) and the lower rail (5). The upper stop element (36) form-fittingly engages with the end stop (40, 40b) when the end stop (40, 40b) is reached.

Claims20

Dependent claims

A longitudinally adjustable vehicle seat comprising:

a lower rail;
and
an upper rail which can be displaceably guided along the lower rail in the longitudinal direction within a comfort adjustment region;
an end stop mounted on the lower rail;
a screw head located in a cavity between the upper rail and the lower rail;
and
a stop module comprising a stop element mounted on the upper rail, the end stop delimiting the comfort adjustment region by cooperating with the stop element mounted on the upper rail, wherein by shifting the stop element away, from a bottom of the lower rail and lifting beyond the end stop, the upper rail is able to be displaced beyond the comfort adjustment region into an easy entry region, and wherein the stop module is pivotable about a pivot axis and comprises a deflector element, wherein the stop module is configured such that when the stop element has not been shifted away from the bottom of the lower rail and lifted beyond the end stop, the deflector element moves upward in a vertical direction upon contact with the screw head which is located in the cavity between the upper rail and the lower rail, and the stop element acts positively on the end stop when the end stop is reached.

4 more elements

A longitudinally adjustable vehicle seat comprising:

a lower rail;
an upper rail movably mounted on said lower rail in a longitudinal direction of said rails along a comfort adjustment region and an easy entry region, said lower rail and said upper rail defining a cavity between each other;
an end stop mounted on said lower rail;
a stop element pivotally mounted on said upper rail about a pivot axis, said stop element delimiting said comfort adjustment region by cooperating with said end stop, said stop element being pivotal away from a first position at said lower rail to a second position beyond said end stop allowing said upper rail to be displaced from said comfort adjustment region into said easy entry region;
an obstruction arranged on said lower rail in said comfort adjustment region, said obstruction protruding away from said lower rail toward said upper rail by a distance to block movement of said stop element toward said easy entry region when said stop element is in said first position;
a deflector element moving said stop element from said first position to beyond said obstruction when said deflector element and said stop element move across said obstruction, said deflector element not moving said stop element from said first position when said deflector element and said stop element move across said end stop.
